Abstract:
Disclosed is a method and apparatus for provisioning a label switched path (LSP) between two endpoints executing a first set of MPLS functions. The method and apparatus associates a first node with the first endpoint and a second node with the second endpoint. The first node is designated as the source. Both the first and second nodes execute a second set of MPLS functions, wherein the second set of MPLS functions include the first set of MPLS functions and additional MPLS functions. As the source, the first node provisions a first MPLS path (i.e., LSP) between itself and the first endpoint. The first node then provisions a second MPLS path (i.e., LSP) between the first node and the second node. The first node then transmits a message to the second node instructing the second node to provision a third MPLS path between the second node and the second endpoint. The three MPLS paths are bridged at the first and second nodes to complete the LSP between the two endpoints.
